Abstract (en)
The present invention relates to a solid laundry detergent composition comprising: (a) from 20wt% to 39wt% detersive surfactant selected from anionic detersive surfactant and/or non-ionic detersive surfactant; (b) from 10wt% to 40wt% inorganic salts selected from sodium carbonate, sodium sesquicarbonate, sodium bicarbonate and any mixtures thereof; (c) optionally, from 10wt% to 40wt% citric acid and/or salts thereof; (d) from 0.001wt% to 1.0wt% lipase that is a variant of SEQ ID NO:2 comprising: (d)(a) substitutions T231R and N233R and (d)(b) at least three further substitutions selected from D27R, N33Q, G38A, D96E, D111A, G91Q, G163K, E210Q, D254S, I255A, and P256T; where the positions correspond to the positions of SEQ ID NO 2 and wherein the lipase variant has at least 95% but less than 100% sequence identity to the polypeptide having the amino acid sequence of SEQ ID NO: 2 and wherein the variant has lipase activity, wherein at 1wt% dilution in de-ionised water at 20°C, the composition has a pH in the range of from 7.6 to 10.0; wherein at 1wt% dilution in de-ionised water at 20°C, the composition has a reserve alkalinity to pH 7.5 of greater than 3.0, wherein the composition is in the form of a coated laundry detergent particle that is curved and has perpendicular dimensions x, y and z, wherein x is from 0.5mm to 2.0mm, wherein y is from 2.0mm to 8.0mm, and wherein z is from 2.0mm to 8.0mm, wherein the coating comprises the inorganic salt (b), and wherein the core comprises the detersive surfactant (a).
